That's amazing!! That you should phrase it like that: "Lily wasn't armed"!! That's something I've been ... well, not really thinking about but has been lurking JUST outside my thoughts!! Did Lily have her wand?? Did she perform the protection CHARM with her wand??? Kinda have to I reckon.

Jo's said that "the fact that Lily's wand was good for charms will be important". Why didn't she just say 'Lily was good at charms"??? Why her "wand"??? Where are the Potters' wands?? (they can break. Hagrid's and Ron's are evidence of that. Did the wands go bang when they did??) Where are the Potters' bodies/ graves??

We're meant to find out "all we will ever need to know' about 'that night' so I guess we'll see

What do you think of the theory (pretty old now but still...) that Voldy owed Lily a 'wizard debt'/life debt which she passed on to harry by sacrificing herself for him??? I don't know. Just one of those whimsical, out there, we won't ever really know 'til thebooks but it's fun to pass the time away theorising, kinda things. Still ...????
